CzmlUnitQuaternion

Provides methods for working with a unit Quaternion defined in CZML.

See:

Members

<static> doublesPerInterpolationValue

The number of doubles per packed value used for interpolation.

<static> doublesPerValue

The number of doubles per packed Quaternion value.

Methods

<static> getValue

Given a non-sampled unwrapped interval, returns a Quaternion instance of the data.

Parameters:

Name	Type	Description
`unwrappedInterval`	Object	The result of CzmlUnitQuaternion.unwrapInterval.
`result`	Cartesian3	The object to store the result in, if undefined a new instance will be created.

Returns:

The modified result parameter or a new Quaternion instance if result was not defined.

<static> getValueFromArray

Given a packed array of x, y, z, and w values, extracts a Quaternion instance.

Parameters:

Name	Type	Description
`array`	Array	A packed array of Quaternion values, where every four elements represents a Cartesian3.
`startingIndex`	Number	The index into the array that contains the x value of the Quaternion you would like.
`result`	Cartesian3	The object to store the result in, if undefined a new instance will be created.

Returns:

The modified result parameter or a new Quaternion instance if result was not defined.

<static> getValueFromInterpolationResult

Given a packed array of axis-angle rotations returned from CzmlUnitQuaternion.packValuesForInterpolation, converts the desired index into a unit Quaternion.

Parameters:

Name	Type	Description
`array`	Array	The array containing the packed axis-angle rotations.
`result`	Quaternion	The object to store the result in, if undefined a new instance will be created.
`sourceArray`	Array	The source array of the original Quaternion values previously passed to CzmlUnitQuaternion.packValuesForInterpolation.
`firstIndex`	Number	The index previously passed to CzmlUnitQuaternion.packValuesForInterpolation.
`lastIndex`	Number	The index previously passed to CzmlUnitQuaternion.packValuesForInterpolation

Returns:

The modified result parameter or a new Quaternion instance if result was not defined.

<static> isSampled

Returns true if this interval represents data that should be interpolated by the client or false if it's a single value.

Parameters:

Name	Type	Description
`unwrappedInterval`	Object	The result of CzmlUnitQuaternion.unwrapInterval.

<static> packValuesForInterpolation

Given a packed array of x, y, z, and w values, creates a packed array of Cartesian3 axis-angle rotations suitable for interpolation.

Parameters:

Name	Type	Description
`sourceArray`	Array	The packed array of quaternion values.
`destinationArray`	Array	The array to store the packed axis-angle rotations.
`firstIndex`	Number	The index of the first element to be packed.
`lastIndex`	Number	The index of the last element to be packed.

<static> unwrapInterval

Returns the packed Quaternion representation contained within the provided CZML interval or undefined if the interval does not contain Quaternion data.

Parameters:

Name	Type	Description
`czmlInterval`	Object	The CZML interval to unwrap.
